Purchase World of Warcraft at Best Buy, get Burning Crusade free

Hey, if you've made the important life-altering decision to sell your soul (and all your free time) over to World of Warcraft, you might as well go whole hog, you know? Best Buy's got a pretty scintillating deal for the 40-or-so people left on the planet who've yet to play Blizzard's super successful MMO: For a limited time, if you purchase the core game for $20, you'll get the Burning Crusade expansion (which retails for $30) at no additional charge. It's like getting twice as addicted at half the cost! What a steal!
